Using battery alarms
You can configure the computer to warn you when the battery is
running low. There are two alarms available:
❖ Low Battery alarm
The Low Battery alarm gives you an audible warning when
the computer’s battery has about 10 percent of its charge
remaining. You can set the volume (off - low - medium - high)
for the low battery alarm.
❖ Critical Battery alarm
The Critical Battery alarm notifies you when the computer’s
battery has about five minutes remaining. You can choose
whether the Critical Battery alarm gives you an audible and/or
a visible warning.
To modify the default settings in the Power utility, click Start,
point to Settings, and click Control Panel. Double-click the
Power Saver icon, then click the Alarms tab.
Changing the main battery
When the battery runs out of power:
❖ If AC power is available, run the computer from the AC
source while the battery charges, or shut down the computer
and allow the battery to recharge.
❖ If you have charged a spare battery, change the battery.
CAUTION: Handle battery packs carefully to prevent damage
to the casing. Avoid dropping the battery or mishandling it.
Also, be careful not to short-circuit the battery terminals.
